Abstract
An industrial robot of the horizontal multi-articulation type includes a vertical shaft providing an articulation between a first arm and a second arm. The shaft is supported for rotation at a fixed vertical position on the first arm while the second arm is removably secured through clamping to an end portion of the vertical shaft second arm which projects downwardly from the first arm. The bottom end of the shaft is supported by a removable bearing plate. A pulley operatively connected to a motor is mounted for rotation on the shaft, and a speed reduction gear is interposed between the pulley and the shaft so that the shaft and hence the second arm are angularly rotated by the motor at a very low speed relative to the speed of the motor. In this arrangement, the second arm can be easily mounted and removed on and from the shaft and hence the first arm.
